View Original AbstractShort-term cell phone radiation showed no immediate effects on brain blood flow, but longer-term impacts remain unstudied.
Plain English Summary
Finnish researchers used advanced brain imaging (PET scans) to measure blood flow in the brains of 15 healthy men while they were exposed to cell phone radiation at 902.4 MHz for 5 minutes. The study found no changes in brain blood flow patterns, even though the radiation did cause a slight temperature increase in the ear canals. This suggests that short-term cell phone exposure doesn't immediately alter how blood circulates through the brain.
Study Details
The present study investigated the effects of 902.4 MHz Global System for Mobile Communications (GSM) mobile phone radiation on cerebral blood flow using positron emission tomography (PET) with the 15O‐water tracer.
Fifteen young, healthy, right‐handed male subjects were exposed to phone radiation from three diffe...
The exposure induced a slight temperature rise in the ear canals but did not affect brain hemodynami...
The results provided no evidence for acute effects of short‐term mobile phone radiation on cerebral blood flow.
